1. Landry Bender and Kevin Hernandez as Blithe and Rodrigo Pedulla, The Sitter (2011)
The Sitter makes its intentions quite clear early in the film. This is going to be, quite simply, 80 minutes of said sitter Noah's (Jonah Hill) charges giving him the absolute hardest time imaginable. We knew that going in. What we didn't know is just how insufferable the kids would actually be, especially the youngest two, sociopath Rodrigo and would-be party girl Blithe.
Before the 50-minute mark, Rodrigo has blown up the bathroom in a fancy restaurant and stolen drugs from one of the weirdest dealers in all of cinema, and Blithe labels Noah a pedophile and abductor for the fun of it. By the end of the film we vowed to never volunteer to watch kids again.
